Malco Sheet Metal Double Enter Drill Bits

Tough Bits. Designed for drilling sheet metal, Malco's Sheet Metal Double Ender drill bits are perfect for ductwork, metal flashing, and gutters. At only 2 inches long, they're tough to break — and when one end gets dull, you can use the other end. They come in a polished finish in sizes from 1/8 to 1/4 inch and in black nitride in 1/8-inch and #30 sizes. A 12-pack of 1/8-inch black nitride bits sells for $21.
